It's not possible
From UIPageViewController.h
// An array of UIGestureRecognizers pre-configured to handle user interaction. Initially attached to a view in the UIPageViewController's hierarchy, they can be placed on an arbitrary view to change the region in which the page view controller will respond to user gestures.
// Only populated if transition style is 'UIPageViewControllerTransitionStylePageCurl'.
@property(nonatomic, readonly) NSArray *gestureRecognizers;
Notice the Only populated if transition style is 'UIPageViewControllerTransitionStylePageCurl'.
Here you have a workaround
UIPageViewController returns no Gesture Recognizers in iOS 6
